ECM technologies, Pleasant Prairie, Wis., will deliver a low-pressure carburization and high-pressure gas quench system to Mercury Marine of Fond du Lac, Wis. This is part of the latter’s plan to upgrade its heat-treating capabilities with a move to the low-pressure carburization and high-pressure gas quench system.
The new plan incorporates completely automated Nano vacuum heat-treating systems that incorporate 20 bar nitrogen gas quenching along with low-pressure carburizing (aka vacuum carburizing). The Nano, with its versatile configuration, will operate several different carburizing, hardening, and spheroidizing processes simultaneously. This change marks a departure from Mercury’s traditional atmospheric carburization and oil quench system while benefiting from advantages that come with vacuum processing:
The system uses all CFC workload fixtures and ECM’s advanced automation fixture tracking to maintain a precise cycle count to know fixture life. This improvement for Mercury significantly reduces energy consumption and process cost per piece. Additionally, the vacuum process takes their heat treatment to near-zero-emissions for drivetrain components processed within the system.
